摘要:
The invention relates to a method and apparatus for removing bark balls from a log flow traveling on a conveyor (3) which extends from a debarking drum (1) to a chipper (2), said conveyor (3) including a roller assembly (4) provided with an opening (5) for dumping from the conveyor (3) a sub-flow consisting of wood pieces and bark balls. The apparatus comprises an adjustable dispenser device (6) for further dividing the sub-flow falling from the conveyor (3) into a portion including mainly wood pieces and a portion including mainly bark balls.
摘要:
An improved log debarking apparatus characterized by a pair of shafts with cleated wheels for supporting and rotating a log under a rosser type debarking tool. The improved log debarking apparatus further has a plurality of log lifters movably supported about a common axis, and each having a profiled upper edge engageable transversally with a lower surface of a log on the cleated wheels. There is also provided a first lifter actuating means for alternately turning the log lifters from a retracted position below a radial projection of the cleated wheels, to a raised position above the cleated wheels, and into a log ejecting position wherein each profiled upper edge is inclined for rolling the log along and away from the cleated wheels. There is further provided a second lifter actuating means for moving the plurality of log lifters longitudinally relative to the shafts. The present invention also relates to a method for debarking a log, comprised of the following steps: raising the log above the cleated wheels; moving the log until a large lump on a surface of that log is positioned beside any of the wheels; laying the log back onto the wheels; and rotating the wheels and the log, and debarking the log.
